Description

  The present invention relates to a solar cell panel laying structure capable of efficiently discharging heat from a space on the back side of a solar cell module to prevent a decrease in power generation efficiency of the solar cell.

In recent years, with the aim of mitigating global warming, among the greenhouse gases that are the cause, in order to build a society with low carbon dioxide (CO ₂ ) emissions (low carbon society), conventional resources such as oil and coal There is a growing social momentum that spreads renewable energy using sunlight instead of energy that relies on energy. In addition, a mechanism has been established in which governments and local governments actively assist with the demand for introducing solar cell modules, and power companies purchase excess power.

In a solar cell module that efficiently uses sunlight, it is known that the power generation efficiency of a solar cell decreases when the back surface becomes high temperature.
Therefore, as shown in Patent Document 1, a plurality of “holes” are formed in all the frame members 2 positioned on the peripheral edge of the solar cell module 1 to form the communication portion 3, and the back surface side of the solar cell module 1 is formed. The thing which suppresses a temperature rise by making each space communicate with each communicating part 3 is proposed.

JP 2000-101120 A

However, in the structure described in Patent Document 1, the air flowing from the “hole” on the eaves side, the “hole” on the side, or between the roofing 7 and the horizontal rail 4 is directed toward the ridge direction. Although it flows, it can be discharged only at the uppermost part of the solar cell, that is, the building side, so that sufficient exhaust cannot be performed.
In addition, since exhaust is affected by the amount of inflow of air, when the wind speed is low or the amount of inflow is small (small), the amount of exhaust is reduced and sufficient exhaust cannot be performed. It stayed inside.
Furthermore, since “holes” are formed in all the frame members 2 in the eave building direction and the left-right direction, there is a possibility that sufficient strength cannot be obtained.

  Then, this invention aims at providing the installation structure of the solar cell panel which can discharge | emit heat quantity efficiently from the space of the back surface side of a solar cell module, and can prevent the fall of the power generation efficiency of a solar cell. .

  The present invention has been proposed in view of the above, and a solar cell panel that is provided with a frame body having a side wall at the periphery of the solar cell module and is opened on the back surface is provided on a take-out fitting attached to a folded plate roof. A step-by-step laying structure by laying in an inclined manner so that a communication space communicating with the folded plate roof in the flow direction is formed, and the back surface side of the communication space and the solar cell module The space is continuous, and among the frame of the solar cell panel, the upper frame and the lower frame in the flow direction are provided with openings, and the solar cell panels adjacent in the flow direction are spaced at regular intervals. The solar cell panel laying structure is characterized in that an open portion is formed by being laid and an upright portion protruding from the surface of the solar cell panel in a laid state is provided below the open portion. is there.

  In the solar cell panel laying structure according to the present invention, the opening is a partial or constant-width vacant portion formed in a lower portion of the side wall, or a plurality of holes formed in the side wall. We also propose a solar panel laying structure.

In the construction structure of the solar cell panel of the present invention, the air (heat amount) on the back surface side of the solar cell module can be discharged from the opening provided in the upper frame, and the air flowing on the surface of the solar cell panel at the standing portion. By forming the turbulent flow in the flow, the effect of sucking out the air on the back surface side can be achieved, so that the temperature rise of the solar cell can be suppressed and the decrease in power generation efficiency can be prevented.
In addition, since the solar cell panel is stepped by laying in an inclined manner, the solar cell panel can be installed at an angle at which sunlight can be received efficiently, and at the upper end of the back space of the solar cell module Since the inclination gradient also becomes strong, air (heat amount) can be discharged more easily.

  In addition, the opening can be formed very easily when the opening is a partial or constant width void formed in the lower portion of the side wall or a plurality of holes formed in the side wall. In particular, in the former mode, the empty portion can be used as a space through which the cable of the solar cell module passes, and can be guided to the back side of the solar cell module without blocking rainwater, snow accumulation, or the like. Moreover, in the latter aspect, it can be used also as an attachment location of the fastening bolt for fixing with locking vertical pieces, such as a fixing member along the water upper side of an upper side frame.

  The present invention provides a solar cell module having a side wall on the periphery of a solar cell module, and attaches a solar cell panel whose back side is open on a carry-out bracket attached to the folded plate roof in the flow direction between the folded plate roof. It is a laying structure that is stepped by laying in an inclined manner so as to form a communicating space, wherein the communicating space and the back side space of the solar cell module are continuous, and the solar cell panel Among the frame bodies, the upper frame and the lower frame in the flow direction are provided with openings, and the solar cell panels adjacent in the flow direction are laid at regular intervals to form an open portion. An upright part is provided on the water side of the part.

The solar cell module used in the present invention may be a module obtained by laminating solar cells such as a crystal system on glass or the like, or may be a thin film such as an amorphous film. Further, it may be formed into a sheet shape (plate shape) or a board shape by being integrated with a metal plate or the like as a base material.
As the solar cell, a single-sided light receiving type is generally used, but a double-sided light receiving type may be used in order to increase the amount of power generation. In this case, if a reflective part is interposed below the solar battery module, Good.
Further, the frame body is composed of an upper frame, a lower frame, and left and right side frames arranged on the four sides of the solar cell module, and each frame body includes a holding unit that holds the periphery of the solar cell module; And a side wall depending downward.
And it was set as the solar cell panel which provided the said frame body in the periphery of the said solar cell module, and the back surface side open | released.

  The “opening” in the present invention may be a partial or constant width void formed in the lower part of the side wall, or a plurality of holes formed in the side wall, and can discharge air on the back side of the solar cell panel. If there is no particular limitation. In the former mode (empty portion) and the latter mode (hole), the forming method and the shape thereof are not limited, and processing such as cutting, punching, drilling, or the like may be performed from the lower end. The height may be previously shortened (compared to the side frame), or may be molded so that a void or a hole is formed in the side wall in advance.

In the former aspect, since this opening (empty part) is formed between the base and the base in the arrangement state, this empty part can be actively used as a space for passing the cable of the solar cell module. . Moreover, the opening part (empty part) of this aspect can be made to flow under water without blocking rainwater, snow accumulation, and the like, and can therefore be led to the back side of the solar cell module.
In general, in order to connect adjacent solar cell modules, a process such as cutting out a part of the frame body is performed in order to pass the cable. However, in this aspect, such a process is not required.

In the latter mode, the opening (hole) is also used as an attachment location of a fastening bolt for fixing to a locking vertical piece such as a fixing member or an attachment member that runs along the water side of the upper frame in the installed state. be able to.
In general, the water-side edge of the solar cell module is fixed by holding the upper end of the upper frame with a holding piece (part) provided on a fixing member or the like. However, in this configuration, there is a problem that dust or the like easily accumulates because the pressing portion protrudes.
In this aspect, an opening (hole) is provided in the side wall of the upper frame, and a fastening bolt can be attached to the opening (hole). Nor.

As described above, the object of the present invention is to efficiently discharge heat from the space on the back surface side of the solar cell module to prevent a decrease in power generation efficiency of the solar cell. What is necessary is just to be formed between a solar cell panel and a foundation | substrate, and height width may be formed partially large by the shape of foundation | substrates, such as an exterior structure which has a wavy or a raising part. In addition, the solar cell panel may be directly laid on the substantially flat base and may be a substantially uniform thin space surrounded by the solar cell module and the peripheral frame body. It may be formed between a substrate on which a supporting member such as a horizontal beam or a vertical beam is attached and the solar cell panel.
In any backside space, air (heat quantity) warmed in the space tends to move to a higher position, so that an opening is provided in the upper frame in the flow direction as described above. Thus, air (heat amount) warmed in the space can be released to the outside. In addition, the inflow of the air from the outside to this space is performed from any surrounding direction except the aspect which lays a solar cell panel directly with respect to the above-mentioned substantially flat base | substrate. In a mode in which the solar cell panel is directly laid on the substantially flat base, it is desirable to provide an opening in the lower frame to allow air to flow.
Moreover, such a back surface side space may be continuous or independent in the eaves-ridge direction, the carry-out direction, or both.

The above-mentioned configuration in which the solar cell panels adjacent in the flow direction are laid at a constant interval to form an open portion is different from the configuration in which the solar cell panels adjacent in the flow direction are spaced apart at a constant interval and opened.

By doing so, you may make it form the open part of a fixed space | interval.
In addition, “provided with an upright part protruding from the surface of the solar panel in the laid state on the windward side of the open part” means that generally the roof slope, the flow direction of the roof surface from the ridge side to the eave side is completely On the contrary, it indicates that an upright part is provided on the windward side of the blown-up wind blown from the eave side to the ridge side, that is, on the water side in the open part.

The standing part provided in the open part may be provided in all open parts or may be provided partially. Further, the standing portion may be provided over the entire length or partially provided with respect to the side of the solar cell. Further, the standing portion may be substantially vertical with respect to the surface of the solar cell, or may be inclined inward and outward. Further, the standing portion may be a substantially flat standing piece, or an arcuate (curved surface) or stepped standing piece.
In addition, the upright portion may be molded integrally with the frame body itself, or may be attached as an external member, or may be integrated in advance with an attachment member or the like. , Fastening of bolts and nuts, etc., fitting, engagement, adhesion, or a combination of these may be used to indirectly attach to the base, or even a separate upright part may be tightened together with a mounting member, etc. Good.

  And by providing this standing part in the adjacent space | interval (opening part) of a solar cell panel, the wind which hit the standing part raises a turbulent flow upward, and makes the upper end of a standing part into a pressure-reduced state, The air in the back space is sucked out from the opening to the front surface side, the flow of air in the back space is significantly accelerated, and the temperature at which the solar cells themselves are generated can be suppressed to prevent a decrease in power generation efficiency. .

In the second embodiment, the upper water end portion of the lower solar panel 1 ″ is disposed (placed) on the support horizontal piece 67 formed on the water side of the vertical surface portion 65 of the mounting member 6B. Since the upper end of the vertical surface portion 65 is fixed so as to abut the lower end of the upper solar cell panel 1 ″, the solar cell panel 1 ″ is laid in an inclined manner. For fixing the panel 1 ″, a substantially Z-shaped pressing member 5H was placed along the upper end of the lower frame 14 ″ of the solar cell panel 1 ″ and fixed integrally to the fixing piece 66 with bolts 7g and nuts 7h.
In addition, when mounting the water upper end of the lower solar cell panel 1 ″ with respect to the support horizontal piece 67 of the mounting member 6B, the water upper end (vertical edge) is abutted against the locking vertical piece 68. In the installed state, the fastening bolt 1c is fixed to the opening (hole) 110 "using the washer 1b and the nut 4d in the same manner as in the first embodiment. Further, the upper end of the vertical surface portion 65 can be stably disposed so as to abut the lower end of the upper solar cell panel 1 ″. That is, the mounting member 6B is the same as in the first embodiment. Similar to the attachment member 6A, the solar battery panels 1 ″ and 1 ″ are held at a constant interval (opening portion 15) and can be easily arranged to perform a position regulating action and a gap holding action.

  In the second embodiment, the same effect as that of the first embodiment is achieved, and the opening 110 "is formed by a plurality of holes. Therefore, there is no projecting portion and the design is excellent, and no dust or the like is deposited. In addition, since the solar cell panel 1 ″ is stepped by laying in an inclined manner, the solar cell panel 1 ″ can be installed at an angle at which sunlight can be efficiently received, and the air in the back space 16 of the solar cell module 10 (The amount of heat) can be discharged more easily.

FIGS. 9A to 9C show typical arrangement examples of the solar cell panel 1 in the present invention, in which the right side of the drawing is the water side, the left side is the water side, and from left to right. A case where the wind is assumed to blow exclusively is shown, and the air flow is indicated by thick white arrows.
FIG. 9A is an example in which each solar cell panel 1 is arranged in a substantially parallel shape, and the reference example 1 corresponds to one example, but the air flowing on the surface of the solar cell panel 1 at the upright portion 2. By forming a turbulent flow in the flow, the air 16 on the back surface side is discharged from the open portion 15 close to the upright portion 2.
FIG. 9B is an example in which each solar cell panel 1 is arranged in an inclined shape that raises the upper side in the flow direction, and the first embodiment corresponds to one example, but in the space 16 on the back side, The back surface of the solar cell panel 1 flows in an inclined manner and is discharged from the opening 15.
In FIG. 9C, each solar cell panel 1 is substantially parallel as in FIG. 9A, but the solar cell panel 1 provided with the upright portion 2 is not provided with the upright portion 2 below the water. This is an example in which the battery panels 1 are arranged close to each other, and the flow of air flows as if the length of the solar cell panel 1 is doubled, and the air 16 on the back side as in FIG. 9A. Is discharged from the open portion 15 adjacent to the upright portion 2. Thus, the standing part 2 may be provided in all the open parts 16, or may be provided partially.
